The first table below shows the historic counties and their administrative sub-divisions before the first round of changes and lists the successor counties for each, that is the post-change counties which contain some or all of the original county area. The second table shows the counties after the first round of changes and lists their successor unitary authorities. In all cases only the top-tier authority is shown - either the top-tier in a two-tier arrangement or a single tier authority (shown italicised).
Additional information is provided where appropriate and available - the common abbreviation for the area; and the Chapman County Code (CCC), a unique 3 letter code for counties and regions.
For a brief description of the administrative changes in the United Kingdom see - Local Government Changes in the United Kingdom.
The following abbreviations are used in these tables:
| Key | |
|---|---|
| (C) | County Borough |
| (U) | Unitary Authority |
Single-tier local authorities are shown italicised.
The links in the following table are to outline maps showing the location of each county.
